My Mt Vernon AE insert has an igniter problem. It’s actually an igniter control problem. The igniter stays red hot at all times. Occasionally I will get the min fire pot temp fault and it’s red hot even then while the fault is displayed on the wall board. The heater works I just know the igniter should shut off after the start cycle is complete. This probably explains why I’ve gone through so many igniters. Has anyone fixed this problem?
